As Sister Hazel frontman Ken Block continues to bask in the glow of the recent birth of his son, Chance, the band's new single, "Change Your Mind," continues to climb the pop radio charts, setting the stage for next week's release of "Fortress," Sister Hazel's new album.

MTV News recently caught up with Block and Sister Hazel guitarist Ryan Newell, and the two talked about the genesis of "Change Your Mind," a track that helped kick-start the final round of recording sessions for "Fortress."
